DETROIT, MI - The singing hot dog vendor, a fixture at Detroit Tigers games for the past 15 years, tweeted Friday he was fired.

Charley Marcuse is known to Tigers fans for an operatic voice that sings his sales pitch up and down the aisles of Comerica Park. Marcuse, who tweets as @SinginHotDogMan, tweeted Friday:

"After 15 years the @Tigers finally got what they've aways wanted: I was fired by @delawarenorth #Sportservice this morning. #LongLiveMustard."

Most fans reacted sadly to the news Marcuse would no longer sell at games, but the singing vendor had his detractors. Along with the attention-getting voice, Marcuse was known for chastising fans for putting ketchup on hot dogs. He frequently tweeted the hashtags #noketchupinbaseball and #longlivemustard.

Here's a selection of fan reactions to the end of the singing hot dog man's time at Comerica:
